High-temperature pressure-resistant clay bricks

Factory direct sale heavy refractory high alumina brick industrial kiln with high temperature resistant high alumina brick standard brick   The main production of clay bricks, high alumina bricks, silicon carbide bricks, corundum bricks lightweight clay bricks, lightweight mullite bricks, etc., tunnel kiln 4, the annual output can reach more than 80,000 tons!   Clay brick Al2O3 content is generally more than 40%, Fe2O3 content is less than 2.0 ~ 2.5%. The clinker in the ingredients is 65～85%, and the combined clay is 35～15%. The crushed combined clay and finely ground clinker mixing and grinding, and then with particles of clinker together with the preparation of semi-dry mud, high-pressure molding, firing at about 1400 ℃, better performance. Clay bricks are weakly acidic at high temperatures and slightly less resistant to alkaline slag erosion, but enhanced with the increase in Al2O3 content. Thermal stability is better than silicon bricks, magnesium bricks (see magnesium…
